Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Pi eCard Logo

Pi eCard is the easy POS (Point of Sale) system for the Pi Network, enabling in-person vendors and Pioneers to invoice others without the need to type in long public keys. The status of the payment can be seen at any stage by both the vendor and the client for pi network.

Quick Start

Get your API keys

Your API requests are authenticated using API keys. Any request that doesn't include an API key will return an error.

You can get your API keys in your dashboard at any time, visit developers to generate or get your keys.

See an example of how to use our package

const { PieCard } = require('@decentapps/piecard')

// Initialization
const piecard = new PieCard("Client_ID", "Client_Secret", "Access_Token");

// CREATE PAYMENT
const paymentData = {
  amount: NUMBER, // amount of service >= 0
  memo: STRING, // memo of the transaction
  metadata: OBJECT // key-value pairs of metadata
};

piecard
  .createPayment(paymentData)
   .then((result) => {
     console.log("Create payment response : ", result);
  })
  .catch((err) => {
    console.log("Response error : ", err);
  });

// GET PAYMENT BY ID
const paymentId = STRING // 63e064aebc26563e677a9ae1
piecard
  .getPaymentById(paymentId)
  .then((result) => {
  	console.log("Get payment : ", result);
  })
  .catch((err) => {
    console.log("Get payment error : ", err);
  });

// SEND PI FROM APP TO USER (APP-TO-USER TRANSACTION)
const appToUserData = {
  amount: NUMBER, // Will be deducted from your wallet, plus the 0.02 Pi fee
  recipient: STRING, // Either Pi Username OR Wallet Address
  wallet_public_key: STRING, // Your Mainnet wallet address
  wallet_secret_key: STRING, // We will never see or store this
  memo: STRING, // Optional - this will appear on the blockchain
};
piecard
  .makePaymentToUser(appToUserData)
  .then((response) => {
    console.log("Pi Payment response : ", response);
  })
  .catch((err) => console.log("Sending pi to user error : ", err));

// GET A SECURE PAYMENT PAYLOAD
const encryptedData = STRING;
piecard
  ._decryptPayment(encryptedData)
   .then((result) => {
     console.log("Decrypted Payment response : ", result);
  })
  .catch((err) => {
    console.log("Decrypting Payment error : ", err);
  });
